Thawing permafrost covering almost a quarter of the northern hemisphere could “significantly amplify global warming” at a time when the world is already struggling to reign in rising greenhouse gases, a U.N. report said on Tuesday.

Most of the northern hemisphere is ocean, but the UN report is close enough for government work. The important thing is that according to the UN, the land areas are mostly frozen wasteland – and are going to belch out massive amounts of methane and kill us all.

It is already happening! And this is on top of the fact that all Himalayan glaciers will be gone by 2035 ™UN.

Happens all the time …
“The ground is perennially frozen here, as it is also farther south. When summer comes and the ice surface melts, the water is not absorbed. It is repelled by the frozen subsoil, which acts like impenetrable cement. The ground water accumulates and covers the land as far as the eye can see. The rivers are overburdened with water and they cannot drain the entire vast territory. This is the most forbidding part of the Siberian Arctic.”http://trove.nla.gov.au/ndp/del/article/67354553
